Cold Foil Finishing
Cold foil is an astonishing innovative print technique that enables you to apply metallic foil, in-line, at press speed, in an countless scope of colors. Cold Foil Finishing can be applied using two normal offset printing units. The first unit uses its inking unit and an offset printing plate to implement glue either as a spot application or to the complete sheet.
The second, real cold foil unit incorporates take-up and take-off units for utilizing the foil. Right with the sheet, the foil is fed into the nip between the blanket and the impression cylinders and put on by pressure to the places on the printing stock coated with glue. As soon as the backing is removed, the metal layer remains on the sheet. The remaining printing units are used to overprint the sheet. CMYK and spot colors can be printed on the surface of the sheet and over the foil.The result is a fantastic foil effect.
Drip-off and Hybrid Coatings
Conventional inks are used for the process colors. A special-effect print varnish is applied in the last printing unit to the places that should have a matt appearance. Then, the coating unit is used to apply a conventional full-area high-gloss coating that drips off the places previously given a matt coating. This maintains the matt result of these sections and offers the remaining spots a gloss surface.
Hybrid or UV inks are being used for the process colors. An added printing unit is used to implement a UV special-effect print gloss to the areas of the picture that are to have a matt appearance. Next, the coating unit is used to implement a full-area UV high-gloss coating. Because a UV high-gloss coating is used for hybrid applications, a better gloss intensity may be achieved than with a drip-off application produced by using a conventional, water-based high-gloss coating. With hybrid applications, however, the structure of the matt effect is stronger compared to drip-off applications.
Hybrid and UV Spot Coatings
UV inks are being used for the process colors. An extra printing unit applies a hybrid special-effect print varnish to the areas of the picture that are to have a matt appearance. After that, the coating unit is used to apply a full-area UV high-gloss coating. The matt effect is generated exactly where the gloss coating 'sinks' into the special-effect print varnish.
UV inks spot-coated with a UV matt varnish in a added printing unit are employed for the process colors. Next, the coating unit is utilized to implement a UV high-gloss coating as a second spot coating. This clearly differentiates the matt and gloss areas. As a UV high-gloss coating is utilized for the hybrid application, the gloss level is corresponding to that reached with the UV application. The matt effect in the hybrid application, however, has a surface which is less soft than with the UV application, recognized as a hybrid effect.
